For those of you who are under the MCU1/HW3 combo - what are you using to view the dashcam footage? Is there something you did with specifivally did in formatting your USB drive? Thus far I know it's getting written, but I cannot seem to find a decent viewer that I can use on a Windows machine.
I actually like to use this web-viewer. It syncs all the cameras together and then plays it all at once so you see all sides. I noticed that it doesn't really play on google chrome so you might have to try EDGE/SAFARI.
